Benefits of technology
The present invention is about a liquid crystal display device with a narrow bezel, which means the device has a smaller edge. The invention includes a display panel, a light source, a mold frame, a bottom chassis, a driving part, and a driving circuit board. The invention also includes a flexible circuit board to connect the driving circuit boards. The flexible circuit board has an insulating film, circuit wiring lines, and contact holes. The technical effect of the invention is to provide a display device with a narrower bezel.
Problems solved by technology
However, in recent years, the size of liquid crystal display devices has increased, causing the liquid crystal display device to become thicker and hence, the driving part to become longer.
When the length of the driving part is increased, the manufacturing cost rises and workability in outer lead bonding (OLB) and module processes deteriorates.
If the circumferences of the plurality of liquid crystal display devices in a multi-vision or dual monitor are thick, the portion of the area occupied by the circumferences in the entire screen increases, resulting in deterioration of the picture quality.
However, this results in a liquid crystal display panel having an increased circumference because of the thickness of the circuit components and the gap.

Embodiment Construction
[0029] The invention is described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure is thorough and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like reference numerals in the drawings denote like elements.
[0030] It will be understood that when an element or layer is referred to as being “on” or “connected to” another element or layer, it can be directly on or directly connected to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on” or “directly connected to” another element or layer, there are no i...

A display device includes a display panel provided with an electrode pad, a light source to emit light to the display panel, a mold frame to support the light source; a bottom chassis to accommodate the mold frame, a driving part to apply a driving signal to the display panel connected to the electrode pad, and a driving circuit part that controls the driving part. The driving circuit part includes a first driving circuit board connected to the driving part and on which circuit components are mounted toward the mold frame, and a second driving circuit board connected to the first driving circuit board. The display device further includes a flexible circuit board to connect the first driving circuit board and the second driving circuit board.
Description
CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority from and the benefit of Korean Patent Application No. 10-2006-0089480, filed on Sep. 15, 2006, which is hereby incorporated by reference for all purposes as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a liquid crystal display device including a liquid crystal display panel that has printed circuit boards (PCBs) arranged along adjacent sides of the liquid crystal display panel. [0004] 2. Discussion of the Background [0005] In general, a liquid crystal display device displays a desired image on a liquid crystal display panel using light emitted from a backlight unit by adjusting the light transmittance of liquid crystal cells, which are arranged in the form of a matrix, according to an image signal. [0006] A liquid crystal display device includes a liquid crystal display panel having liquid crystal cells that form pixels arr...
